The district formed in 1933 as a consolidation of three school districts called West Linn Union School District. This included Stafford School, Bolton School, and Willamette School, which still exist today (though in different buildings), and West Linn Union High School, which was renamed to
West Linn High School in 1938.
Wilsonville was also consolidated into the district, which at the time only had one K-8 school, Wilsonville Primary School. At the time, the city was unincorporated with only a few hundred residents. High schoolers had to take a bus to West Linn. When the city was incorporated in the 1968, Wilsonville began seeing significant growth. Wilsonville Primary School began to see overcrowding, and so Inza R. Wood Middle School opened in the 1980's. High school students still required to take a bus to West Linn, and residents were begging for the district to open a dedicated high school in the city.
Wilsonville High School finally opened in 1995. Since then, two new primary schools and a middle school have opened, and Wilsonville Primary School closed upon the opening of Boones Ferry Primary School. In 2025, the district phased out the middle school choice zones. Previously, fifth grade students at some Primary Schools in West Linn had a choice between Athey Creek Middle School and Rosemont Ridge Middle School. This created problems, as multiple school buses had to be sent to the same area, increasing costs. The only choice zone remaining is a choice zone between Boeckman Creek and Stafford, which will eventually become the boundary for a new primary school. ==Demographics==
